` any nut and have a tendency to turn or .mar

the corners or crush orotherwise disfgnre the fixusli asy when melrelplating or japan coating is used. The acljustahle wrenches,

pliers and tongs are slow'iaeperation, do f not grip and` hold the nutrods, or pipes promptly and efficiently` and tendto'work open inoperation, makingit necessary to repeatedly adjust'thexn tothe work;`with the exception of a few Wrenches of the ratchet`type which have butlil'nitedapplin iati'on and but narrow range of utility, all wrenchesknown to me require to -be withdrawn from the workjand a new grip`found. Y afterw moving' the `Work a small distance.

for the purposes for whichv the ordinary monkey wrench is commonly used,but'is adapted toserve such purposes in a better manner. On inspectionot' Fig. 1 more pargroo/ved as indicated at 13 to receive the.

tieularly it will be observed that I provide a shank having at-one end ahandle 11 and.

at theo'ther end a jaw 1.2. The shank- `10`is shank 14 of the opposingjaw 15 which is slidably mounted therein and provided with' For holdingthe jaws 12 and '15 in predetermined pof as indicatedvat 22, adapted toengagev with the ratchet teeth 16. For normally holding sitlon I employa bifurcated lever 17,-pi voted to the shank 10, as indicated at 18, andenavin b means of'a )in 19 the slot 20 in a, g n g l sliding b ck S21provided with ratchet y,teeth the members 14and 21 in contact, and inengagement by means of the teeth 16 and '22. I employ a sliding yoke 23slotted on each side, as at 24 and 25, for engagement with th'eprojecting Aends ofthe pins 26 and 27. 27*

respectively carried bythe .shank 10 and the block 21. To hold theyoke23 in 'adjusted' position I provide thereon a spring 28 providedWitlr a projecting portion 38 adapted to engage notches 30 formed in theshank' 10 and in providing means :tor holding the toothed portion22ofthe,blo`ck 2l in en-r gagement with the toothed lportion 16 of theshank 14 I employ a spring'Bl riveted to the.

yoke 23 Aat 32 and havinga downward projection 34 passing through anaperture 35 in such yoke and bearing upon the face 36. ot` .such-slidingblock21. For locking the memfreely relatively to the shank 10 I cnt awaythe said shank 14,' as indicated at41, and insert therein a spring l42bearing on the bottom 43v of the said shank 10. In the operation ofthe'wrench above described itwill be understood that when theyoke 23 1smoved outward as far as the slots 25 will permit,

the pins 27`and'27 .hold it'in .the depressed position shown so as toprevent,k the toothed faces/16 and 22 from disengagement and therebythejaws 12 and '15; from rela 'tive longitudinal movement. Likewise thatwhen the yoke is moved inwardlya short distance the pins 27, 27 willtorce it upward sufficiently to allow the teeth -16 and 22 `'to passeachother,b'ut.the spring 31 will continue to press upon the face -36 ofthe'block 21 suliciently tomaintain engagement'and prevent movement ofsuch blockto inward. though permitting the .movement thereof outwardsince the ratchet teeth 22 tend lto,

above explained.

` and 15a having suitable l curved and toothed;

slide over the teeth, 16; Furthermore that" whenthe yoke 23 is'moyedfarthest inward, the block 21 is raised suflicientlyto entirelydisengage the teeth 1G an'd 22, and permit movement of the-block 21 ineither' direction. Similarly that by virtue of the extension 88 ofthe'spring 28, striking the pawl 37,' such pawl is thrown outofenga'gement with the toothed portion 39 of the vlever 17. From theforegoing description it will be observed that in the use offa wrenchembodying my'. invention in the form above described, the yoke 23 isdrawn farthest inward, allowing theready disengagement ofthe members 21and 14, and thus relativemovement ofthe jaws 12`and 1 5 which arethenset at as close as possible an approximation ofthe correct .distanceapart, the handles being then first arranged in a convenient positionfor operation,. and afterward slightly opened. The yoke 23 is-thereuponmoved outward andthe handles l1 `and 44 of the' 'sliarilnl10 and the.lever 17 arebroughttogether as'far as may be necessary to hold thenutor other object engagech It will likewise be observed that inasmuch asthe pivot p in 18 is fixed andthe pivot 19 movable to the left 'in theapproximation of the-handles 11 and 44, thus mov ing the jaw 15 towardthe jaw 12, any pres sure tending to draw the handles togetherisproportionately transmitted to the jaw l5 and thus that the greater,the' presslire/jeta'-` erted -upony the' handle 44 in the operatic otthe device', the greater the pressure ex ted upon the nut or other'object engaged.

)[oreover, h when the yoke. 23 is in the position shown mere separationof the handles 1l and `44 opens th'e jaws suliciently to changethe hold,or if desired, gain ahold at a different angle, without removing the 105`Jaws from the work.- In vork1ng onirregularly shaped objects by` movingthe sleeve until'the pins occupy positionsl relatively to .I

the slots indicated'at 2G' andf27the jaws may be opened wider by' virtuev'of .the ratchet action between the lteeth'l and 22 As is'- clearly tobe seenon reference to Fig. 1. by virtue of the disposition of"cutting"v edges 45 and 4 6 lon the jaws v1 2 and 15 the device aboverdescribed maybe lfadily'used asaw'ire cutter.

#Referring noir' more paiticularly to the device of Fig'. 5 oninspection ofthis ligure it will be noted 1thatbyl providing jaws 12engaging surfaces, indicated'at 41,48 andv 49v and 5Q, re"spectively,'the surfacesd?
